Reduce size

The file opt.sqfs contains Xorg, Xfce, Fluxbox and all GUI programs. When you don't need them, then
just remove the opt.sqfs file. It's optional and not required to boot.

It's also possible to build a custom Live version and strip binaries, remove programs and so on. You find more details
in the Build Live Release article of the Build Tools section.
4.2. Reduced size describes how to build a smaller Live Version of Plop Linux.
